Jira issue: CRDB-68370

Start by reproducing sql/physicalplan.TestFakeSpanResolver with race=true, run=1, and shard=3, then inspect the stack trace and the related failures listed in the report. Trace the timeout through the mentioned RPC, KV, and transaction-wait paths; done means identifying the cause and making the test pass reliably.
